UNITED STATES HENRY JANSSEN, OF WYOMISSING, PENNSYLVANIA, ASSIGNOR TO TEXTILE MACHINE WORKS, OF WYOMISSING, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

STAMPING- MACHINE.

Application filed February 20, 1924. Serial No. 694,151.

To all whom it may concern:

Be it known that I, HENRY JANSSEN, a citizen of the United States, residing at WVyomissing, in the county of Berks and State of Pennsylvania, have invented certain new and useful Improvements in Stamping Machines, of which the following is a specification.

My invention relates particularly to stamping mechanism employing an electrically heated die adapted for marking stockingsor the like; and it consists in providing an advantageous device in which the structure extending above the operating table comprises merely a die-carrying tube to which the vertical presser movement is imparted and through which concealed conductor wires are passed to the die heating coil; as fully set forth in connection with the accompanying drawing and clearly defined in the subjoined claims.

Fig. 1 is a partly sectional elevation of my improved device applied to a table, the section being on the line 11 of Fig. 2.

Fig. 2 shows an elevation at right angles to Fig. 1.

To the operating table a, is fixed a guideway bearing 6, which is shown as extending upwardly through an aperture in the table with its lower bolting flange 0 having fixed thereto depending spring-holding rods old and a connecting bottom cross-bar e to support coil springs f on said rods.

The movable stamping device, as indicated, consists merely of a die-carrier tube 9 which is vertically slidable in the fixed bearing 6 and in the centrally apertured spring supporting cross-bar c; said tube having a fixed cross-head h which is guided upon the spring-holding rods d d and bears upon the springs f so that the latter will act to retract the downwardly pressed diecarrier tube. The upper portion of this tube 9 is bent to horse-shoe shape, as indicated, and has a suitable stamping die is with heating-coil portion m for electrical connections, secured to its down-turned end;

while the depending lower portion of the tube is provided with suitable operating means, as a stirrup device a, for imparting stamping movement thereto. To prevent a jarring stoppage of the spring-retracted movement of the stamping device a cushion seat a is provided for the cross-head h.

The usual electrical connections pp for the die-heating coil, extend from the latter wholly within the tube 9 to a lateral passageway s at the lower end of the tube; through which they may extend to a fixed resistance coil, not shown, for controlling the heat as usual. This lateral passage way 8 to the interior of the tube, is formed integral with a bottom fitting 25 having a connection 4) for the operating means a, and the mouth of said passage way is provided, as indicated, with an insulating ring w for the passing wires.

It will be seen that in my improved device, only the smooth upper portion of the tube 9 with the heated die attached thereto, appears above the table, which is highly desirable in the handling of material to be stamped as well as for neat appearance.

What I claim is:

1. A stamping device comprising a fixed guide-way bearing, a reciprocatively operated die-carrier tube vertically slidable in said bearing and having a down-turned upper portion provided with a coil-heated die, and conductor wires extending within the tube from the die-heating coil to a passageway therefor at the lower portion of the tube.

2. A stamping device comprising a fixed guide-way bearing, spring-retracted die-carrier tube vertically slidable in said bearing and having a down-turned upper portion provided with coil-heated die and a depending portion provided. with a pedal attachment having a lateral wire passage way, and conductor wires extending through said passage-way and tube to die-heating coil.

In testimony whereof I aifix my signature.

HENRY J ANSSEN.
